-# Cosmos SDK v0.42.9 "Stargate" Release Notes
+# Cosmos SDK v0.42.10 "Stargate" Release Notes
 
-This release includes an important `x/capabiliy` module bug fix for 0.42.7 and 0.42.8 which prohibits IBC to create new channels (issuse [\#9800](https://github.com/cosmos/cosmos-sdk/issues/9800)).
-The fix changes the `x/capability/keeper/Keeper.InitializeAndSeal` method behavior and requires to update an app module manager by adding x/capability module to Begin Blockers.
+This release includes multiple performance improvements, such as:
 
-We also fixed `<app> init --recovery` mode where the mnemonic was not handled correctly.
+- improve ABCI performance under concurrent load via [Tendermint v0.34.13](https://github.com/tendermint/tendermint/blob/master/CHANGELOG.md#v03413),
+- improve CacheKVStore datastructures / algorithms, to no longer take O(N^2) time when interleaving iterators and insertions.
+- bump IAVL to v0.17.1 which includes performance improvements on a batch load.
 
-We also changed `<app> tx distribution withdraw-all-rewards` CLI by forcing the broadcast mode if a chunk size is greater than 0. This will ensure that the transactions do not fail even if the user uses invalid broadcast modes for this command (sync and async). This was requested by the community and we consider it as fixing the `withdraw-all-rewards` behavior.
+We also fixed the keyring to use pre-configured data for `add-genesis-account` command.
 
-See the [Cosmos SDK v0.42.9 milestone](https://github.com/cosmos/cosmos-sdk/milestone/53?closed=1) on our issue tracker for the exhaustive list of all changes.
+Finally, when using the `client.Context`, we modified ABCI queries to use `abci.QueryRequest`'s `Height` field if it is non-zero, otherwise continue using `client.Context`'s height. This is a minor client-breaking change for users of the `client.Context`.
